In Science we are learning about the Nervous System

The nervous system is a very, very important system in the human body because it is the part of the body that tells your arms and legs to move, your eyes to blink and your mouth to form words. It lets the body feel things, if you stub your toe or get tickled the reason you can feel it is because of the nervous system. The two main parts of the nervous system are the brain, and the spinal cord. The brain is located inside of your skull and your spinal cord is a bundle of nerves surrounded by bones called vertebrae. When you touch something, a neuron is stimulated. It creates an electrical impulse that travels from neuron to neuron using chemicals called neurotransmitters. Did you know that in the time it takes for you to say misisipi three times, an electrical impulse could travel across a football field and back? We would like to learn more about some of the diseases associated with the nervous system and what causes them.
